Wandering Giant Troll first seen at Dunegrass Farm, purported to have abducted the missing Halfling girl Esther Dunegrass in Jolev.

A muscular, twenty-foot-tall woman with thick green skin and protruding tusks is grabbing pigs from a nearby pen, snapping their necks with a flick of her thumb, and tucking them into a massive leather sack. - Taron's Trophy (RPA-ADV2) 

The truth is that she and her partner Songak had taken a sick Esther in, found lost and becoming her caretaker.

Urka is especially caring, and any crimes she may have committed in the eyes of the citizens of Jolev were only to tend to Esther Dunegrass;

However, she is also more than capable of adopting a more offensive frame of mind if the situation calls for it;

They have been kind, Esther says, but she doesn’t speak their tongue well enough to explain her situation.

Your approach startles the beast, but she is quick to her defense. Brandishing her sack of hogs like a mace, she meets your attack with a deafening roar. - Taron's Trophy (RPA-ADV2)

Like many Dragul, Urka is a gentle individual unprovoked;

Urka was kind to the Dunegrass girl, who was sick with fever. A strong and compassionate soul, Urka will be missed by many Dragul, but by none more than her partner, Songak. - Gate of Brizoor Waal (RPA-ADVF)

Urka is found at Dunegrass Farm, raiding their livestock:

• Attack the Giant Troll:
  • You slay her.
  • She overpowers you and flees.
• Intimidate the Giant Troll:
  • You scare her into submission.
  • Urka makes her plea:
    • Move to attack her:
      • You slay her.
      • She overpowers you and flees.
    • Allow her to lead you to her retreat.
  • She runs away.
• Observe the Giant Troll:
  • You follow her to her lair.
  • She loses you.

If she lives, you find yourself at her cave, where her partner Songak awaits her:

• If you fought Urka and slayed her, Songak will lash out upon seeing her blood on you.
• If you fought Urka and she got away, the two Giant Trolls will lash out upon the threat of your arrival.
• If you befriended Urka, the two will show you to Esther Dunegrass and share a meal, communicating that they have been taking care of her. They leave you with a parting gift, a sword called Grintaker.

If a conflict arises:

• And you return to Sabek with two heads having slayed both Giant Trolls, even Zalic will be impressed.
• And you are overpowered, Esther intervenes, and the Dragul will flee, allowing you to rush the Halfling girl back to Jolev.

If Urka and Songak fled Jolev, they are next met in Sabek laying waste to the city - Tome of Encounters (RPA-Tome-ADV4-8)

• If you attacked the Giant Trolls before, they will lash out, enraged:
  • Attempt to talk them down, appealing to their humanity:
    • Succeed, and befriend them now, conveying your apologies. Songak leaves you with a parting gift, a sword called Grintaker.
    • Fail, and fight for your life.
      • You are able to take them down.
      • You are crushed by them and left for dead in the streets.
  • Prepare to fight:
    • You are able to take them down.
    • You are crushed by them and left for dead in the streets.
• If you killed Urka and Songak survives her, she will attack:
  • You are able to take her down, claiming a sword called Grintaker as a trophy.
  • You are crushed by her and left for dead in the streets.
• If you befriended the pair:
  • They take a moment to greet you warmly and offer some of their loot before carrying on with their business.

If you slayed Urka at Dunegrass Farm outside Jolev, the Demon Elsifor unleashes her angry spirit on you to fight. - Tome of Encounters (RPA-ADV6-6)

If Urka lives, she fights against King Taron, atop a megapede, and Urka in Nebblis, Plane of Flame:

• If you side with the Dragul, you will fight alongside her:
  • If you defeat the opposition and are favored by the Giant Troll, she will greet you with care. You claim the site, and find a red rune.
  • If you defeat the opposition and are disfavored by the Giant Troll, you will earn her approval and claim the site, finding a red rune.
  • If you fall to the opposition, you stumble through a rift back to Elsifor's Tent at Brizoor Waal in defeat.

You are met be a crusade of children, clothed in rags and carrying buckets filled with stones. Kalso, the costumed clown, follows behind tossing candy in the air. If you beheaded Urka earlier, he will toss a papier-mache head in your direction. It clearly resembles Urka.

• Wear her head. The children start to pelt you with their stones.
  • Try to stop them.
  • Run away.
  • Hide behind Kalso.
• Refuse and the audience will boo you mercilessly while the children pelt you with their stones.
